Title: Method and device for manufacturing magnetic disk cartridge
Inventor: YAMASHITA KAZUHIKO
IPC: G11B23/033
Filed: 1989-03-13
Abstract: PURPOSE:To remove a residual object at a maximum as much as possible by applying ultrasonic vibration to a half case and a liner before welding, separating the residual object or making the residual object separatable, next, jetting air, sucking the residual object and removing the object. CONSTITUTION:An ultrasonic wave is oscillated and the ultrasonic vibration is applied through an oscillating horn 5 to a half case 2 and a liner 1. Then, the residual object remained in the liner 1 is separated or made separatable. Next, the air is jetted to the half case 2 and liner 1 and the floating residual object is sucked and removed. Accordingly, since dust is removed from the liner 1 before a pair of the half cases 2 are welded by the ultrasonic wave, the jetting amount of the air is not limited. Thus, the residual object such as the dust in the case 2 can be removed at a maximum.

Title: Method for measuring waveform of cornea potential chart
Inventor: USUI SHIROU
IPC: A61B3/10
Filed: 1988-03-15
Abstract: PURPOSE:To measure a characteristic parameter by separating an accurate OP wave by applying real time waveform data processing due to a moving averaging method and a differentiation method to the rhythmic small wave superposed on an (a)-wave and a (b)-wave different in delay with respect to light stimulation. CONSTITUTION:An ERG waveform is differentiated to calculate a differential waveform and the peak intervals T1, T2, T3 of the OP wave superposed on the (b)-wave are calculated from the zero cross points of the differential waveform and the arithmetic mean thereof is set to a mean cycle T of the OP wave. ERG waveforms are subjected to moving average on the basis of the mean cycle T and this mean value is subtracted from the original ERG waveform to extract a temporary OP wave component which is, in turn, differentiated to determine the first peak point P and temporary start point A of the OP wave from the zero cross points thereof. The waveform after the A-point is rotated by 180 deg. around the A-point to be extended and subjected to moving mean on the basis of the cycle T to connect the original waveform to the calculated waveform and a waveform wherein the OP wave component is removed is obtained. The A-point is successively moved and a point A<n> at the time when a smooth waveform can be given is set to a start point B and the obtained waveform is subtracted from the original ERG waveform to obtain a waveform only of an OP wave component.

Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To provide a communication terminal capable of easily judging a used state of a B channel by always monitoring only the B channel signal transmitted from an ISDN network to an information terminal. SOLUTION: A change of the B channel is compared with B channel data by the octet stored at the previous frame by a comparator 16 and when the change is judged to exist in its output result, a judgment signal h indicating that the B channel is at the used state is outputted by a first detecting circuit 12. Difference between the B channel and discrimination data by the octet in a free state of the ISDN network is judged and when a pattern like a flag or a mark is detected from the data by the octet in the discriminated free state by comparators 32, 33, the judgment signal is outputted by a multi-vibrator 35 by securing time grace exceeding a timer value of transmission/reception of bi-directional data to confirm normality of the data transmission/reception by a second detecting circuit 20.

Title: Electric field relaxing apparatus and electric apparatus
Inventor: YOSHIDA TETSUO
IPC: H02B13/02
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To suppress an electric field strength and to reduce the size by changing the permittivity of an insulating layer, so as to decrease successively from one electrode side to the other electrode side. SOLUTION: The permittivity of the whole insulating layer is changed in stages so as to decrease from one-end electrode 15 side to the other-end electrode 15 side. Incidentally. the movable contact of a disconnector 4 is operated, by linking an operating board 11 to the end electrode 15 with a linking pin 12, and converting the rotating motion of the operating board 11 into horizontal motion by the linking pin 12. Potential gradation in the insulating layer becomes smaller, and an electric field strength around the end electrode 15 lowers, by changing the permittivity of the whole insulating layer in stages, so as to decrease from the one-end electrode 15 side to the other-end electrode 15 side, in an electric field relaxing apparatus. Especially on the surface of the end electrode 15, its electric field strength lowers by the influence of the insulating layer. Consequently, it becomes possible to reduce the size of the electric field relaxing apparatus itself, by suppressing the electric field strength of the end electrode 15, and the electric file strength of the insulating layer.

Abstract: PURPOSE:To accumulate coins stably and orderly to prepare wrapped coins excellent in quality by automatically displacing, by a distance almost coinciding with the thickness of carried-in coins, a support means capable of carrying coins in a layered state. CONSTITUTION:The number and coin characteristic values of coins C passing through a carry-in path 13 by a carrier belt 14 are detected by a magnetic sensor 15. According to time detected characteristic values. a thickness data conversion means 101, to which the values are reported, calculates the thickness dimensions of the circulating coins C and communicates them to a comparison command means 102.
